Study on correlation prediction model for static explosion and dynamic explosion shock wave pressure

Blog Article

In actual combat, the attack of the warhead on the target is a dynamic process, and there is a significant difference in shock wave pressure between dynamic and static explosions of ammunition, while dynamic explosions are more in line with actual combat situations.Therefore, conducting research on the distribution law of dynamic explosion shock wave pressure in ammunition has more practical value for evaluating the damage power of ammunition and guiding its use.This study used the display explosion dynamics simulation software AUTODYN to conduct simulation analysis on the pressure Food allergy knowledge, attitudes and their determinants among restaurant staff: A cross-sectional study. distribution patterns of static and dynamic explosion shock waves, clarifying the differences in pressure distribution between dynamic and static explosions.Considering the factors that affect the distribution law of dynamic explosion shock wave pressure, a BP neural network based correlation prediction model for static and dynamic explosion shock wave pressure was constructed, and the prediction accuracy of the model was verified.

The analysis results indicate that the pressure distribution of dynamic explosion shock waves has a significant velocity Sovereign CDS Premiums’ Reaction to Macroeconomic News: An Empirical Investigation tendency; The prediction accuracy of the static and dynamic shock wave pressure correlation prediction model based on BP neural network is better than 90.7%.The research results have improved the accuracy of the calculation of dynamic explosion shock wave pressure in warheads, providing effective calculation methods and scientific data support for the calculation of dynamic explosion shock wave pressure and the evaluation of damage power.
